Junction Temperature, Tj

(2)

151 °C

Notes:

1. The thermal resistance is referenced from the hottest part of the junction to the backside paddle.

2. This corresponds to the typical biasing condition of +5V, 400 mA at an 85 °C case temperature. A minimum

MTTF of 1 million hours is achieved for junction temperatures below 247° C.

Product Marking

The component will be lasermarked with a

“VG112-G” designator with an alphanumeric

lot code on the top surface of the package.

Tape and reel specifications for this part will be

located on the website in the “Application

Notes” section.
